G5X-3 114 Question?
I have this cam sitting in my garage but I'm having second thoughts about putting it in. Partly b/c it's so big as far as lift and duration for a stock cube motor and the question of streetability and reliability will arise. I have over heard some people talking about how the car want make good power and torque until much higher rpm's. I won't something that I can drive evryday but at the same time I want a cam that is going to make good times at the track. What would you guys suggest, keep what I've got or go with a smaller cam?
BTW, I was going to spray nitrous occasionally with the X3 which is part of the reason that I went with the 114 LSA. Also I have some 2.5 heads that will be here friday if that makes a difference in your decision.

Ahh - Go ahead and stab it in. Godspeeds video does it for me every time. $$ permitting - I will do a cam some day - just to hear it scream to near 7000 RPM :steering:

I think with good tuning and good springs, streetability and reliability will be fine.
If you go smaller, and then soon wish for more like most people seem to do, you'll be kicking yourself later.
It seems the old school "don't overcam" rule of thumb has now been replaced with "go one step bigger than what you think you want". Just an observation I've made reading the various forums.
A year from now this might be considered a mild cam, who knows.
I'd keep it, it's a good choice and a proven powermaker, both on the dyno and on the dragstrip.

Drop me a PM or email with your questions. I have this cam in my car now.
As you can see from my sheet there is power to be had across the whole spectrum. And I think with a little more tuning I can get that dip out.

Re: G5X-3 114 Question? (Z06ufgrad2002)
Do you wished you would have went with a smaller cam with more torque under the curve or does the hp make up for it? My heads are suppose to be here friday so I would like to have whatever cam I'm going to run by then.

Re: G5X-3 114 Question? (Bone_Stock)
I also drive my car with the G5X-3 as a daily driver. the torque at low end is no compromise, since it exceeds the stock Z06 at all rpms. plus it makes huge gains from about 4000 rpms and a 45 ft lb increase at peak torque.
It is very tame as a street driver, especially on a 114.
I think you will enjoy it and the new found power that you'll get with this easy upgrade.
Thanks

I can hardly wait until April 14th when I bring my C5 up to your shop for the G5X-3 w/lsa 114 Cam Pkg. w/Comp 921 Dual Springs, and Vig2800 (w/B&M Trans Cooler) install. Chris & Jeremy (Godspeed) convinced me this set-up would reach my 400rwhp/rwtq goal, yet be very daily driver friendly.
BTW, April 12th is my 43rd birthday, so I know you will foot the bill on a chocolate cake for my belated b-day/400rwhp party on the 17th when I come back to your shop for my C5. :lol:

Unless you are running some serious tire out back; any more torque than what I presently have is not going to do any good since the tires will just go up in smoke.
So you really need to think about where you are headed and what you plan to do with the car. If you are going to 1/4 mile the car a lot then this is the cam for you. If you are just looking for a cam will low end torque for tire smoking then maybe you need something else. If you are running a 345 in the rear then you will be ok with more torque.
My car pulls like crazy above 3000 rpm and when it hits 4500; it pulls even harder.
The only thing I wish I did differently was either go with the high-flow cats or saved my Ti mufflers. My car is so loud now above 2500 rpm with the Borlas that I am very hesitant to put my foot into it; for fear of attracting the WRONG kind of attention. ie the law man.

Did you mean 3.42 rear, rather than 3.45 rear? Not busting your chops just trying to learn all I can about the G5X-3 upgrade, since I'll be doing same in April. One of my first mods was LGM changed out my 2.73 rear to 3.42 rear.
BTW, I apologize for not remembering the tires your running but are my Kumho MX's in the same category as your tires?
I wonder if the RT Matrix HF Cats added to your LG Pro LT Header Off Road System would decrease the sound? Personally, I love the sound of my C5 equipped Pro LG LT Header Off Road System hooked up to Borla Stinger w/Quad Tips. Have you considered the Mike Mercury Sound Reduction Mod? http://mikemercury.home.att.net/sound.htm I may do this mod if the sound after the G5X-3 upgrade bothers me as much as it does you.

I have the Kumho on the rear.
As for the Borlas, they have to go so I can put my foot into this car and see what it can do. I will have to work on a video so all can here exactly how loud this thing is.

No, I was referring to tire width not the rear diff.

Well, I suppose you can sell the Borla Stinger, then go back to stock Z06 exhaust. You have heard Godspeed's video clip, right? BTW, did you check out the Mike Mecury C5 Sound Reduction link I posted?

Lou
I spoke to you on the phone this week about the specs of the X3 114 with the double rollmaster. What I'm trying to find out is will a make better ET's with the X2 112 or the X3 114. I notice the X3 114 has a dip in the torque and hp curve around 3500 rpm. I know this cam doesn't make power until a higher rpm compared to the X2. Please chime back in with some info. I already have the X3 I'm just waiting on the heads. Do you think I should keep the cam I got or change to a different setup. Remeber I am still looking for streetability and reliability as well
Thanks
Will

This is really the only thing I'm not sure about... I've ridden in one G5X2 car and been around a second (Mike76002) and I think the issue of "daily drivability" is subject to personal preference. For me, the cam was probably too much for my tastes. Add in the fact that I've heard of quite a few springs breaking and mike's car seemed to have cold idle/stalling problems. Maybe it was tuning, but...

1. Who tuned Mike's Car, and
2. how many of the C5s equipped w/G5X-__ cams have you heard of the Comp 921 Dual Springs breaking?
3. or, was it some other grade of Valve Springs?
Godspeed tells me my C5 will not have any cold idle/stalling problems after his tuning. Lou has already mentioned only a very few C5/Z06s w/G5X-__ cam upgrades have had valve spring problems. BTW, none of the valve spring problems with the LGM shop installs, that I'm aware of. He told me the Comp 921 Dual Springs will provide plenty of longevity for my driving characteristics.

Re: G5X-3 114 Question? (Cary)
LG was using the Rev 1116 springs with the G5X2 packages for awhile, and those were the ones people were having breakage problems with.
The Comp 921's have a stellar reputation, but they are pricey.
